LOCKING DEVICE FOR PINS. V

Specification of Letters Patent.

Patented Mar. 28, 1922.

Application filed March 24, 1920. Serialll'o. 368,408. 7

T all 1071 am it may concern:

Be it known that I, Josnr. PnJcHAma citizen of the United States, andresident of the borough of Brooklyn, county of Kings, city and State ofNew York, have invented certain new and useful Improvements in Securingand Looking Devices for the Pins,

of Brooches and other Articles, of which the following is aspecification.

My present invention relates to means for securing and locking the pinsof brooches and other articles. of jewelry orthe like.

The object of my invention isto provide a device which may be appliedreadily to articles of different kinds, which will be strong, simple,and efficient to hold the pin in position, and which will be verycompact so as to be applicablein conditions where but little space isavailable. I

The particularmeans devised by me for carrying out this object will nowbe described in detail with reference to the accompanying drawings,andthe features of novelty will then be pointed out inthe ap- In saiddrawings Fig. l'is a perspective view of a brooch provided with myinvention; Fig. 2 is an elevation of one form of the securing device orholder, in the open position; Fig. 3 shows the same device in the closedposition, with the pin in section; Fig.

l is a section on line 44 of Fig. 2, and Figs- 5, 6, and 7, are sectionson the lines 55, 6 6, and 77 respectively of Fig. 3; Fig.

8 is a vicw'corresponding to Fig. 2 and showing a second form of. myinvention;

Fig. 9 shows the'same form as it appears when looking in the directionof the arrow in Fig. 8; Fig. 10 is a view similar to Fig. 3, showing athird form of myinvention; Fig. 11 shows the same form as seen whenlooking in the direction of the arrow in Fig. 10; Figs; 12 and 13 areviews, partlyin sec tion, illustrating a fourth form of my invention, inthe open and the closedposition respectively; and Fig. 14 is a sectionon the line 1t14 of Fig. 1 r

In each of the forms shown, the device comprises two parts, vine-First,aholder proper adapted to be secured, say bysoldering, to the base A orother suitable portion of the article to which the invention is to beapplied, for instance a brooch, as in Fig. 1...

and adapted to lock in position, the pin B of the brooch or otherarticle;

According to my invention, the holder is made from a tubular piece ofmetal 20, of uniform cross section, which may be circular (see Fig. 7),although cross sections of other shape might be employed. By cutting,sawing, stamping, or any other appropriate operation, I form in suchtube 20, a socket 21 with a narrowed entrance 22 through which the pin Bmay pass. This entrance is adapted to be closed or cleared by thelooking device connected movably with said tubular holder body. Thetubular construction of this body, besides giving it great strength,presents additional advantages as follows, irrespective of whether suchbody is used with or without 'a locking device: First, the endwhich isfitted to the base A.

can be cutoff readily to any length required,

end or attaching end of the holder body can be changedin cross sectionalshape easily by compressionor pinching, or otherwise, so as to conformto the shape of the base A, and particularly'to-the width of suchbase;for instance, if'the tube is originally of circular cross section (as inFig. 7), its attaching end can'be given readily a different crosssection, say an oval one, by pressing this end with a pair of pliers.

The features described so far are shared in common by all the forms ofmy invention shown herein.

Referring now more particularly to the constructions shown in Figs. 1 to11 inclusive, the invention comprises a sliding locking. device movablein suitable parallel tubular guides 23, 23 extending to the outer orfree end of the holder body 20. In each of these cases the lockingdevice is shown as comprising a =U-shaped portion made of wire(preferably circular in cross section), the parallel end members 24., 24sliding in the guides 23, 2-3 respectively, with a fit which issuiiiciently tightto prevent accidental-movement of the locking device.The said device further comprises a plate 25,

nected with the wire rigidly (soldering may be resorted to) and alsoforms a handle for the convenient manipulation of the locking device.The member 24 is adapted to close or clear the entrance 22, according asthe locking device is in its inner or in its outer position.

Diiferent expedients may be employed to limit the outward movement ofthe sliding locking device of Figs. 1 to 11. For instance, in theconstruction illustrated by Figs. 1 to 7, the member 24; (distant fromthe entrance 22) may have its end formed into a stop by bending itinwardly, that is to say, toward the closing member 24, as indicated at27, to come in contact with the narrowed portion 28 of the body 20 whenthe locking device is brought to the outer or open position, Fig. 2. Inthis position, the hook or stop 27 is received within a recess or socket28. In order that this construction may be assembled, the steps of itsmanufacture are as follows: WVhile the body 20 is still of uniform (say,circular) cross section from end to end, the completed locking device isinserted at the outer end of said body, and then said outer end iscompressed or pinched so as to form the contraction 28 and the socket28: as well as the two parallel tubular guides 23, 23, it beingunderstood that at that time the stop 27 is between said contraction 28and the base A. Of course. I might first form the contraction 2S, socket28', and guides 23, 23', and then insert the locking device in anunfinished condition, with both members 2-1, 2% straight to their veryends, the lower end of the member 2 1' being bent subsequently to formthe stop 27; but this operation is not so convenient as the one justdescribed.

According to Figs. 8 and 9, the stop 27 is formed by bending the lowerend of the member 24 outwardly and projecting it through a longitudinalguide and limiting slot 29.

Figs. 10 and 11 show the stop 27" formed by anoutward bend at theloweror free end of the closing member 2%, and preferably the guide tubeor sleeve 23 is formed with a .recess 23 in which said stop finds lodgment when the locking device is inits outer or released position, sothat this stop will not form an obstruction on which thepin B mightcatch as it swings (on its pivot B) into the socket 21.

The operation of these forms of my invention will be understood readily.By

using the plate 25 as a handle, the person can either pull the lockingdevice out to the 7 members 24:, 24; and the guide sleeves 23,

23 being sufiicient to hold the locking device against accidentalmotion, in'either position.

In Figs. 12, 13, and 1 1 the parts 20,21, and 22 are substantially thesame as described above (except that the tubular body 20 is showncompressed to a form which is oval and almost flat in cross section, seeFig. 14.), but instead of the sliding lock, I have shown a lockingdevice or lever 30, 31 pivoted to the'holder body 20 about an axis 32transverse to the length of said body. The arm 30 of the lever forms ahandle for operating the locking device, while the arm 31, when swunginto the position Fig. 12, leaves the entrance 22 open to admit the pin13, whereupon said arm is brought to the looking position, Fig. 13, inwhich it engages the inner surface of the tube 20, being stoppedthereby. In this construction also, friction is relied upon to preventaccidental movement of the locking device.

I claim as my invention:

1. An article provided with a base and a pin connected therewithmovably, and a tubular holder for the free end of said pin, said holderbeing secured to said base and having its axis at an angle to the base,and being provided with a lateral opening for the passage ofsaid pin anda locking member movable in said tubular holder to close or clear saidopening.
